OODA Loop

The OODA loop sequence in decision making is Observe, Orient, Decide, and then Act.

Observe the situation, then orient yourself, decide on an action, then act. This description of a decision making cycle is attributed to Col. John Boyd.

Boyd
states that the orientation phase of the loop is the most important
step, because if the enemy perceives the wrong threats, or
misunderstands what is happening in the environment around him, then he
will orient his thinking (and forces) in wrong directions and ultimately
make incorrect decisions. Boyd said that this cycle of decision-making
could operate at different speeds for the enemy and your own
organization. The goal should be to to complete your OODA loop process at a faster tempo than the
enemy’s, and to take action to lengthen the enemy’s loop.
